Lithium Ion Batteries AA

The big problem that the mobile industry at large is butting its head up against these days is the problem of battery life. These things just aren’t getting better at the rate that processors and other components are, and the more powerful our devices, the more they they demand of their batteries. To make matters worse, batteries tend to lose capacity over time such that after a few years, a full charge may only last a handful of hours. Sony is aiming to tackle this latter problem.

They’re calling it “soft charging,” and it’s a feature we’re seeing on the Beta Marshmallow firmware for the Xperia Z2, Z3, and Z3 Compact. By turning on “Charging optimization” in the settings, your device will deliberately nerf the speed at which it charges. This gentler charging strategy extend your battery’s lifetime.
